Why the 2% inflation target? (2023)

Why a 2% Target (and Not 0%)

• Several argue 2% is a pragmatic buffer: measurement and control are imprecise, so you aim slightly above 0 to avoid deflation.
• Inflation target acts as a coordination / expectations device (a Schelling point): if everyone believes it, wage/price setting is more stable.
• Some note the origin was somewhat ad‑hoc (e.g., NZ’s early “0–1%” remark later nudged to ~2%), then copied globally and retro‑justified.
• Others see it as consciously chosen to allow “stealth” real wage cuts and to erode government debt over time.

Inflation vs. Deflation

• Pro‑inflation side:
  • Deflation raises real debt burdens, risks “doom loops” of delayed spending/investment, and is linked to severe downturns.
  • Mild inflation eases wage adjustments (freeze instead of nominal cuts), helps debtors (esp. fixed‑rate mortgages), and encourages investment over hoarding.
• Skeptical side:
  • Argues moderate deflation driven by productivity can be benign (electronics cited), and that “people will just hoard cash” is overstated.
  • Claims deflation would shift power from asset‑owners to savers; sees anti‑deflation rhetoric as serving creditors and elites.

How Inflation Is Measured (CPI, Hedonics, Substitution)

• Heated debate over CPI:
  • Critics say basket changes, hedonics, and substitution understate “real” cost of living, especially housing, education, and healthcare.
  • Defenders explain methodology (consumer expenditure surveys, changing baskets, regional indices, personal calculators) and stress CPI is a model, not reality, but broadly accurate.
• Boskin‑era changes: one side calls them politically motivated downward tweaks; the other says earlier CPI overstated inflation and that revisions improved accuracy.

Distributional Effects & Inequality

• Many say inflation and the 2% regime disproportionately hurt the poor and lower middle class: wages lag, savings erode, asset prices (especially housing) outrun incomes.
• Others counter that real incomes and material living standards have risen over decades on average, but concede inequality has widened and housing has become less affordable.
• Frequent claim: asset owners and leveraged elites benefit via the Cantillon effect, while cash‑holders and non‑investors lose.

Debt, Housing, and Work

• Inflation seen as:
  • Good for debtors with long fixed‑rate loans; bad for renters and those shut out of credit and asset markets.
  • One driver of ever‑rising house prices vs wages; zoning and NIMBYism cited as separate but compounding issues.
• Broader structural points: globalization, immigration, women’s labor‑force entry, and tech are proposed as key wage/price drivers, independent of the 2% target.

Central Banks, Politics, and Alternatives

• Some view central banks as highly political, using 2% plus money creation to quietly tax savers and backstop financial markets.
• Others argue the main problem is fiscal (deficits, underfunded social systems) rather than the target itself.
• Alternatives floated include: zero inflation with wealth taxes, full wage indexation (e.g., Belgium), permanent ZIRP with fiscal tools, or even “hard money”/crypto; none have consensus support in the thread.
